StarCraft: The Co-Operative Version is a co-operative transformation of all of the vanilla StarCraft campaign maps, including bonus missions not released to the general public! It includes all three campaigns - the courageous Terran's "Rebel Yell", the creepy-crawly Zerg's "The Overmind", and the mysterious, enigmatic Protoss' "The Fall". If you've ever dreamed of reliving the epic saga of StarCraft with a friend fighting at your side, this is your chance to do just that!
I realise that there have already been attempts to make co-operative versions of the StarCraft campaigns, but the users responsible did not deliver as they promised, and their maps were of poor quality. These maps have had far greater amounts of effort put into them, as I can personally attest to, so have no fear: this is not a duplicate!

I haven't heard of this bug, but I'm pretty sure I know why that's happening without even looking at the map. Thanks for your bug report!
Brood War's co-op version is being worked on every now and then. I'll probably release it before June.
